Thanks for the clarification, and reminder for me to recheck my bar size!
I was mistaken. I need 23.8 shifters and cannot confirm that those Microshift thumbs will fit.
Whats's more confusing is that the Microshift website does not clarify the diameter of the "city" shifters (there are separate categories for Road and Mountain and City) and Amazon has two versions available, a MTB and an unspecified.
Need to search for that answer or look into other options.
Thanks again.
